epriestley 4d0935ba5e Rate limit requests by IP ... Summary: Fixes T3923. On `secure.phabricator.com`, we occasionally get slowed to a crawl when someone runs a security scanner against us, or 5 search bots decide to simultaneously index every line of every file in Diffusion. Every time a user makes a request, give their IP address some points. If they get too many points in 5 minutes, start blocking their requests automatically for a while. We give fewer points for logged in requests. We could futher refine this (more points for a 404, more points for a really slow page, etc.) but let's start simply. Also, provide a mechanism for configuring this, and configuring the LB environment stuff at the same time (this comes up rarely, but we don't have a good answer right now). Test Plan: Used `ab` and reloading over and over again to hit rate limits. Read documentation.
